A New Algorithms for Faulted Phase Earthing Protection Relays on 20kV Networks
Mahdi Mozaffari Legha, Saeed Shokoohian
In This paper present mitigate safety issues during a single phase to ground fault, faulted phase earthing (FPE) is implemented on the 20 kV network. Assessment of the present logic functions in the faulted phase earthing (FPE) relays on the 20 kV network. It also outlines the process used to determine if a newly proposed logic algorithm will be sufficient to increase the sensitivity of the relay to pick up high resistance faults without increasing spurious operations.
